DLL Load Library – Error Code 126

by

Windows dll error 126 can have many root causes.
The most useful methods I have found to debug this are:

  1. Use dependency walker to look for any obvious problems (which you
    have already done)
  2. Use the sysinternals utility Process Monitor https://docs.microsoft.com/en-us/sysinternals/downloads/procmon from Microsoft to trace all file access while your dll is trying to load. With this utility, you will see everything that that dll is trying to pull in and usually the problem can be determined from there.
